Mazda6 reliability - how does it compare?

[P5w3kids]

Because existing sources of auto reliability information left much to be desired, in late 2005 I started conducting my own reliability research at TrueDelta.com. TrueDelta reports absolute stats like "trips to the shop" that make the differences between cars much clearer. Results are updated four times a year, so it's possible to provide reliability information on new models like the 2009 Mazda6 quickly. Also, any significant changes in a model's reliability become apparent quickly.

Thanks to the help of this forum's admin and its members, for which I am very grateful, we've been able to provide results for many years of the Mazda6. But more participants are needed to cover all years and break out results for the MS6.

Participants simply report repairs the month after they occur on a one-page survey. When there are no repairs, they simply report an approximate odometer reading four times a year, at the end of each quarter.

To encourage participation, panel members receive full access to the results for free.

Other than a TSB on my wifes 6i clutch...(They replaced it) no problems and we have 22k miles. it's a 2005.

i havent had an problems with it, ive had mine a little over a month maybe 6 weeks or so. its got about 10300 miles

i got it used, its an 06


the only problem that kinda bothers me, is it pretty much drinks gas, the v6 has really poor fuel economy. but other then that, i love it

I noticed a drastic improvement around 20,000 miles. As Ive logged some pretty long trips in the car over the past year the milage has only gotten better. In the city about 21-23 mpg, highway is roughly 28-30.

When I designed my site's fuel economy questionnaire, I assumed that an engine would be broken in by 5,000 miles. 20,000? Wow.

Next update in November. Mazda6 and MazdaSpeed6 owners haven't been as active in the research as those for some other Mazda models, so more participants would help a great deal. If I don't have enough responses for the Mazda6 and MazdaSpeed6, they won't be included in th results.

Just signed up for my 07, they aren't included yet so 07 owners need to participate if they wanna see results.

Other than a couple oil changes, I've had it in the shop once, for a CEL at 2500, when it also got a reflash. No other problems. 11000 on the clock now.

 

[P5w3kids]

Thanks. I guess it might help to post the counts:

2003: 18
2004: 27
2005: 30
2006: 41
2007: 12

Total for all years: 128

Most for any model: 495, for the Honda Accord.

groovy man.

 

[P5w3kids]

Glad you like them.

Latest results in a week or two. For one model year I was a single response short this morning. Sent an email to all owners who hadn't yet responded.

Of course, if more people were signed up, it wouldn't be so close. So, if you haven't signed up to partcipate yet, please consider doing so.

Those results posted here:

TrueDelta Vehicle Reliability Survey results

The 2004 and 2005 have a better than average repair rate. The 2006 is about average, probably because some MazdaSpeed6s are included in the analysis and they are more likely to require attention.

Everyone who helped make these possible, thanks. If you haven't been participating, I hope you'll consider doing so.

well i have 46000 miles on mine and so far everything good been at the dealer for a snap rear axle . other than that just the shutter valve recall and ecu updates . great car compare to some other car similar like evos and sti's in the same horsepower range with friends of mines they seen to have more problems . this is my dayli driver with tracktime events and autoxx also .

 

[P5w3kids]

Updated results have been posted. In this set, the 2006 isn't far off the 2004 and 2005, and is now also better than the average.

We continue to need more participants for all model years.

Next set of results in a couple of weeks.

Additional Mazda6s remain needed. We'd especially like to have a quick result for the new 2009.

I'm glad I found this page. I'm really taking a hard look @ a 06 - 07 Mazda6 s V6. When I saw the transmission issues from owners on Edmunds, I decided to come here. Has anyone here really had any issues with their V6, 6?

 

[P5w3kids]

When you read about problems, it's not possible to tell how common they actually are. Well, in responses to TrueDelta's systematic survey there's no evidence of common failures in the 2004-2006.

Latest results just posted, in terms of successful repair trips per 100 vehicles per year:

2004: 26, much better than average

2005: 17, much better than average, but marginal sample size -- especially need more of these

2006: 45, better than average

We'd like to provide results for all years, including the new 2009, and even break out different engines. But need more participants to make this possible.

Where are the 2009s?

 

[P5w3kids]

I see there's a new section for the 2009s...so maybe there.

We still need more participants with the first-gen cars. Still not enough MS6s to provide a separate result for them, though that would be my personal preference.

TrueDelta has released updated Car Reliability Survey results for the Mazda6.

The 2003 Mazda6 has a repair rate near the average, maybe a bit better. The sample size for this year is very small, so this result is less precise than the others.

The 2004, 2005, and 2006 Mazda6 all have "better than average" repair rates. In all three cases sample sizes are just over the minimum.

We don't have enough participants yet for the 2007, 2008, or 2009.

A big thanks to everyone who has been helping. We'll have further updates in May, August, and November, so additional participants would certainly be helpful. We'd like to have full results for all model years.

TrueDelta now has a separate results page for each model. The one of the Mazda6:
Mazda Mazda6 reliability comparisons

There's also a page with the descriptions of all reported repairs.

I got a 06 MS6 its got 21k on it. I've experienced no problems, I am also very tough on my car. To put it another way Snow=Amusement. lol!
